UNITED STATES PATENT OFFICE.

ABRAM L. OOVEY AND WILLIAM N. GREER, OF ST. PAUL, NEBRASKA; SAID GREER ASSIGNOR TO SAID COVEY.

PLOW.

T 0 all whom it may concern:

Be it known that we, ABRAM L. COVEY and WVILLIAM N. GREEK, citizens of the United States, residing at St. Paul, in the county of Howard and State of Nebraska, have invented certain new and useful Improvements in Plows, of. which the following is a specification.

This invention has for its object an improved construction and arrangement of a laterally projecting blade carried by the landside of a plow and adjustable in a horizontal plane, said blade being designed to eliminate side-draft, and the invention consists in certain constructions and arrangements of the parts-that we will hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following descrip tion and accompanying drawing, in which:

Figure 1 is a side elevation of a plow embodying the invention; Fig. 2 is an enlarged bottom plan view thereof; Fig. 3 is a side elevation illustrating in dotted lines a moldboard and, Fig. 4 is a detail perspective view of our improved blade that is designed to be carried by the land-side.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates a land-side and 2 a mold-board. The land-side 1 is formed in its base edge with a recess 3 and with a shelf 4 projecting inwardly from the upper wall of said recess.

5 designates the blade which is formed as shown with two angularly disposed forward edges and two rearwardly diverging wings. One of the forward edges of the blade 5 is sharpened as indicated at 6, and the said blade is pivotally connected to the lower side of the shelf 4 at the apex of the forward edges of the blade, as indicated at 7, the said blade being accommodated in the recess 3 with one of its wings projecting rearwardly on the inside of the land-side and with its other wing and sharpened edge 6 projecting rearwardly on the outer side of the land-side. At the juncture of the two wings, the blade 5 is formed with an arcshaped Specification of Letters Patent.

slot, receiving a pin 8 secured to the shelf 4:, so that the said blade may be rigidly secured to the land-side with its sharpened edge 6 in different positions in a horizontal plane. Hence it will be seen that the cutting edge may be held at a fixed angle with respect to the land-side and that the amount that the blade projects laterally beyond the land-side may be readily regulated according to the nature of the soil.

In addition to the foregoing, it will be seen that the mold-board 2 of the plow is provided with a yielding extension 9 which is connected to some rigid portion of the plow by a horizontally adjustable rod 10, and it can be set so as to operate in amost effective manner to turn. the furrow. is also shown as engaging the adjustable rod 10 for the purpose of holding the same against vibration. This construction of mold-board forms the subject of a divisional application for patent, filed October 17th, 1907, Serial Number 397,853.

Havingthus described the invention, what is claimed as new is:

The combination of a plow embodying a land-side, said land-side being formed in its base edge with a recess, and a laterally projecting shelf extending inwardly from the upper wall of said recess, of a blade formed with two angularly disposed forward edges and rearwardly diverging wings, said blade being pivotally connected to the shelf to swing horizontally in the said recess with one wing projecting rearwardly on the inner side of the land-side and the other wing projecting rearwardly on the outer side of the land-side, the forward edge of the blade adjacent said lastnamed wing being beveled to form a cutting edge, said blade being formed at the juncture of said wings with an arc shaped slot, and a pin secured to the shelf and accommodated in said slot, as and for the purpose set forth.

In testimony whereof we aflix our signatures in presence of two witnesses.
